.To LZ/f 'uf/w71?, it may concern:

Be it known that I, THOMAS FRAZIER, a citizen of the United States ofAmerica, residing at Hiawatha, in the county of Brown and lState ofKansas, have invented new and useful Improvements in Plate-Securers, ofwhich the following is a specification.

The invention relates to an improvement in plate-securers designed toremovably fix a plate to a table or other support in a manner to preventits accidental displacement.

The main object of the present invention is the provision of aplate-securer which shall be adapted for ready connection with the plateand which will readily accommo date itself to plates of different sizes.

The invention consists in certain details of structure and arrangementof parts which will be described in the following specification,reference being had particularljT to the accompanying drawings, inwhich- Figure l is an edge view illustrating' my improved securerapplied to a plate. Fig. 2 is a plan view ofthe same, the table-clampingmeans being omitted. Fig. 3 is a view similar to Fig. l., though takenin a direction at right angles to said figure.

Referring to the drawingsavherein like reference-numerals indicate likeparts throughout the several views, my securer is mainly formed of wiretwisted upon itself to provide a thickened length of Imaterial of thedesired strength. By preference this portion of the structure is formedof two lengths of wire intertwisted in any desired manner. The length ofmaterial so formed is centrally bent to provide a coil 1, which engagesthe lixed nut 2 of a table-clamp, comprising in addition to said xed nuta clamping-screw 3, provided. at its upper end with the usual head 1, asis usual in clamps of this character. By preference the vfixed nut2 ofthe clamp is formed with an annular recess to receive the coil 1 of thefastener-frame, a tie-bar 5 securing said coil about the nut, asillustrated. From the fixed nut the securer-frame is projectedvertically, both branches of the frame being extended in parallelrelation and preferably in contact, providing branches 6, which. shouldbe of a length sufficient to permit proper operation of the clamp. Theframe at the upper end of the branches 6 is projected forward at a rightangle, as at `7, still in parallel relation, and united at the forwardend of the extension by a keeper 8. Forward of the keeper the heretoforeparallel and contacting members of the frame branch and extend inopposite directions to provide holding-arms9, designed to embrace thedepending bowl 1() of the plate 11. The arms 9 are somewhat less inlength than the circumferential half of the bowl 10, so that when thearms are in place the bowl is embraced for the greater portion of itscircumference. One wire of the two forming the twisted securing framehereinbefore described is projected beyond the terminal of the arm 9,and this projected portion is bent upwardly at an incline and terminallyformed with a hook 12, designed to engage the edge of the plate proper,as clearly shown in Fig. 2. A similar hook 13 is provided im mediatelyadjacent the juncture of the arms 9 with the extension 7 of the frame,the latter hook preferably comprising a single length of wire formed atone end with a hook to engage the edge of the plate and at the oppowsite end bent into U shape to lie on opposite sides of the extension 7and be embraced and held in position by the tie-bar 8, as clearly shownin Fig. 1.

In use the hooks 12 and 1,3 are caused to engage the edges of the plate,the branching arms 9 of the frame underlying the plate and beingarranged concentric with the bowl. The plate is thus held in fixedrelation to the securer and is designed to be secured on the table byengaging the clampingescrew with the edge of the table, the lowersurface of the tie-bar 8 being squared at 14 to rest upon the uppersurface of the table in the necessary coperation with theclamping-screw.

It will `be noted that in the use of my securer` the clamping-arms 9 areconcealed beneath the plate, the hook-terminals being the only visibleportion of the securer, and that owing to the flexibility and springconstruction of the arms 9 the securer will readily accommodate platesof different sizes. Furthermore, when in use the securer preventsaccidental displacement of the plate, though it may be readily-removedfrom the securer by springing the hooks 12 from engagement with the edgeof the plate and withdrawing the plate from beneath the hook 13, as isobvious.

Having thus described my invention, what l claim is- 1. A plate-securercomprising a wire frame secured intermediate its ends to a clampscrew,the arms of the frame extending vertically from the screw in. parallelrelation and IIO being connected by a keeper provided with a hook, theterminals of the frame being projected in the form of curved arms, andhooks connected with the terminals of said arms.

2. A plate securer comprising a clampscrew, a wire trame connected tosaid screw and comprising two lengths oi wire twisted together, theframe being projected from the screw in parallel relation and secured bya keeper, being bent therebeyond to provide divergent clampingarms, oneor' the wires forming a frame being extended beyond the julerminals ofthe arms and bent to provide ooks.

3. A plate-securer comprising a clamping- L screw and secured by atie-bar, said frame being projected beyond said tie-bar to providedivergent clamping arms, hooks secured to the terminals of said arms,and a 100k secured to the frame adjacent said tie- 4. A plate-securercomprising a clampingscrew, divergent clamping-arms arranged in a planeabove said screw, said arms being connected above the screwbya keeper,and aconnection between said keeper and screw,hooks projecting upwardlyfrom the terminals of said arms, and a hook projecting from the keeper.

In testimony whereof I aflX my signature in presence of two witnesses,

THOMAS FRAZIER. Witnesses T. D. SMITH, W. F. CASH.
